CHARLES H. WOLCOTT AND WILLIAM C. STEPHENS, OF THOMASTON, GEORGA. i

DEVICE FOR MOVING WATER FROTJI SLASHERS.

Application filed August 6, 1923. Serial No. 656,127.

T0 all 'whom t may concern:

Be it known that we, CHARLES H. WOL- oorr and WILLIAM C. STEPHENS, citizens of the United States, residing at Thomaston, in the county of Jackson and State of Georgia, have invented a new and useful Device for Moving Water from Slashers, of which the following is a specification.

rlhis invention relates to improvements in slashers, bleaching machines or the like, and aims to provide novel means whereby the steam pressure within the machine may be utilized for forcing condensates therefrom.

An important object of the invention is to provide a device of this character wherein the condensed steam may be forced from the body portion of the machine, while the machine isin operation, eliminating the old and well known trap and bucket type of machine.

Another object of the invention is to provide a valve construction controlled by the movement of the rotary body portion of the machine, so that the valve will be opened at intervals to exhaust fluid therefrom, thereby insuring against the steam employed for heating the body of the machine, passing directly through the machine.

Vith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts-and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of theinvention.

Referring to the drawings:

Figure 1 isa Vfragmental sectional view through one endA of the body portion of a slasher or drying machine.

Figure l 2 is an end elevational view thereof.

Figure 3 is a sectional detail view disclosing the valve operating means.

Figure t is a fragmental sectional view.

throfigh a modified form of the invention. Figure 5 is a sectional detail view disclosing the valve operating means in the modied form of the invention.

Figure 6 is a sectional detail view disclosing the valve operating means in elevation and taken at right angles to Figure 5.

Referring to the drawings in detail, the reference character 5 designates the body portion of the slasher or drying machine,

which is in the form of a drum having openings formed centrally of the end walls thereof, through which openings extends the supporting shaft 6 which is hollow to accommodate a suitable steam supply pipe not shown at one end of the shaft 6. Suitable means not shown, is designed to rotate the body portion 5, so that material placed on the body portion 5, will be carried thereover by the rotation thereof, ythe steam entering the body portion heating the body portion to dry the material passinggthereover.

Extending into one end of the shaft 6 kis an outlet pipe 7 which is curved and formed with a flange 8 that contacts with the packing member 9 disposed between the pipe 7 and shaft 6, to insure a fluid-tight connection therebetween. A. plug 10 is positioned in the shaft 6 to partition the shaft and prevent the steam entering at one end thereof from passing directly through the shaft. The steam is thus directed through the drum to heat the same.

The plug 10 forms a compartment 11 `with the inner end of the outlet pipe 7, the wall of the shaft 10 being formed with a threaded opening to receive the pipe 12 that extends an appreciable distance within the body portion 5, the free end thereof lying in close proximity to the wall of the body portion 5, where the same is submerged in the water shown at the bottom vof the body portion 5.

The reference character 13 designates a valve chamber which has connection with the outlet pipe l7 through the pipe 14, which is shown formed with a threaded extension 15 positioned in a threaded opening formed in the upper end of the valve chamber 13, thereby establishing communication between the valve chamber 18 and outlet pipe 7. A-

valve seat 16 is formed in the valve vchamber 13 and cooperates with the valve member 17 to cut off the passagefof fluid through the valve chamber 13, suitable means being pro,-

vided however for operating the valve member 17 to allow fluid to pass through the chamber, at intervals.

The valve member 17 is mounted at one extremity of the valve stem 18, and as shown,

this valve stem 18 extends through an openingin the rear wall of the valve chamber 13, where the same extends through an opening in the supporting arm 19, the free end thereof lyinP in proximity to one end of the body 5.

The free end of the valve stem n 18 is beveled at 20 and is adapted to be engaged by the cam 21 extending from one end wall of the body so that as the body 5 rotates, the cam 21 will act to slide the valve stem 1S to unseat the valve 17 and allow fluid to pass from the body 5 through the valve chamber and outlet pipe 7 ln order that the valve member may be returned to its seat and normally held closed, a coiled spring 22 is provided and engages the extension 23 formed adjacent tothe valve member 17, the opposite end of the coiled spring 22 embracing the lug 24 of the adjustable cap 25, whereby the cap may, by' a slight rotation thereof, tension the spring 22 to cause the valve 17 to seat under various degrees of pressure.

ln the modied form` of the invention as shown by Sheet 2 of the drawings, the body portion is indicated at 26 and is shown as mounted on the shaft 27 to move therewith, the shaft being provided with a ybore in one end thereof to' receive the coupling 28 which in. turn has connection with the outlet pipe 29. A compartment 30 is formed between one end of the coupling and the wall 31 of the shaft 27, which compartment communicates with the interior of the body portion 26l through a valve chamber 32 `which is connected with the shaft 27 through the pipe 33. A pipe 84 also communicates with the valve chamber 32 and extends to a point in proximity to the wall of the body portion 26 so that water collected in the body portion, due to the condensation caused. by thek steam entering the body portion will submerge the free' end of the pipe 34.

Operating in the valve chamber 32 is a valve stem 35 carrying a valve member 36 at its upper end, a coiled spring 37 being disposed ontheI valve stem 35 and arranged between one wall of valve chamber 32 and valve member 36, so that upon movement of the valve stem in one direction, the spring 37 will `be placed under tension to' return the valve member 36 and normally hold the outlet passage of the valve chamber closed.

Formed on one end of the valve stem 35 is a head 38 that receivesthe forked end 39 of the arm 40, which arm has a ri V`ht angled portion 4.1 that extends through an opening in the end wall of the body port-ion 26, a suitable packing means indicated at 42, beving provided to insure a uid connection between the arm 41 and` walls of the openings in which the same is positioned.

Mounted on the free end of the arm 41 is an arm 43 which is provided with a head 44 formed with a threaded opening to receive the set. screw 45 whereby the arm 43 may be adjustably secured to the arm 41 to adjust the throw of the valve, causing the same to be opened at various degrees.

Secured to the supporting member 46 of the machine is an adjustable screw 47 that lies in the path of travel of the arm 43 so that as the body portion 26 is rotated in the usual manner the arm 43 will contact with the arm 47 to cause the valve 36 to be actuated in a manner as described.

ln the operation of the device, as steam enters one end of the body portion, it is obvious that due to the steam contacting with the relatively cool walls of the body port-ion, condensation will take place, the condensates collecting in the lower portion of the body. It will be obvious that as the steam pressure in the body attains a certain degree, the water or condensates in. the lower portion of the body will be forced into the outlet pipe, the valve member opening at predetermined intervals to allow the condensates to pass from the body, eliminating the old and well known trap and bucket. type of machine.

1. In a device of the character described, a hollow body portion for receiving steam under pressure, a rotatable hollow shaft for supporting the body portion, a pipe in the body portion and having communication with the hollow shaft, a valve member for controlling the passage of fluid through the pipe, and means controlled by the rotation of the body portion for actuating the valve.

2. ln a device of the character described, a hollow drum for receiving steam under pressure, a. rotatable hollow shaft for sup porting the drum, a pipe supported by the shaft and disposed within the drum, a pipe having communication with the shaft at one end thereof, and an automatically controlled valve controlled by the rotation of the` body portion for controlling the passage of fluid through the pipes.

3. ln a. device of the character described, a rotatable hollow body portion adapted to receive steam under pressure, a hollow shaft for supporting the body portion, a pipe supported by the hollow shaft and providing communication between the supporting shaft and body portion, a pipe having communication with the hollow' shaft at one end thereof, valve member supported within the latter pipe, and means controlled by the rot-ation of the body port-ion for actuating the valve to allow fluid to pass therethrough.

In testimony that we claim the foregoing as our own, we have hereto aliixed our signatures.
